Global geometry under isotropic Brownian flows

We consider global geometric properties of a codimension one manifold embedded in Euclideanspace, as it evolves under an isotropic and volume preserving Brownian flow of diffeomorphisms.In particular, we obtain expressions describing the expected rate of growth of the Lipschitz-Killing curvatures, or intrinsic volumes, of the manifold under the flow.These results shed new light on some of the intr

Men at work : Real wages from annual and casual labour in southern Sweden 1500–1850

In this paper, we use a brand new dataset to estimate and compare wages for casually and annually hired workers in early modern southern Sweden. We ask whether men in either situation could have supported families on the basis of their earnings. Findings indicate that casual earners would have been able to out-earn annual employees for most of the period 1500–1850, but by the eighteenth century wh

Statistical properties of spherical wavelets systems

We review some spherical wavelets systems and their statistical properties, with a view to applications in Cosmological/Astrophysical data analysis. In particular, we consider the analysis of Gaussian, isotropic random fields, and we focus on the geometric characterization of wavelet fields emerging in band-limited reconstructions. More precisely, we recall how to provide exact expression for Mink

A discrete view of the Indian monsoon to identify spatial patterns of rainfall

We propose a representation of the Indian summer monsoon rainfall in terms of a probabilistic model based on a Markov random field consisting of discrete state variables representing low and high rainfall at grid-scale and daily rainfall patterns across space and in time. These discrete states are conditioned on observed daily gridded rainfall data from the period 2000 to 2007. The model gives us

Charged jet cross section and fragmentation in proton-proton collisions at s =7 TeV

We report the differential charged jet cross section and jet fragmentation distributions measured with the ALICE detector in proton-proton collisions at a center-of-mass energy s=7 TeV. Jets with pseudorapidity |η|40 GeV/c, the pythia calculations also agree with the measured charged jet cross section. pythia6 simulations describe the fragmentation distributions to 15%. Larger discrepancies are ob

Wavelet analysis of precipitation in an arid, inland river basin

Lack of hydrological data in arid regions is often a huge hurdle water resources investigation. This paper discusses and investigates the long-term rainfall trend by using a nonlinear time series analyses method (Fourier/wavelet and Power Spectrum Analysis) as an alternative way for future research on the prediction of hydrological data.
